KeyError: 'food' in fdc_dm.fdc_data_dict about love

Traceback (most recent call last):

pd_joined = self.fdc_data_dic['food'].join(
KeyError: 'food'

I encounter this KeyError when running run.sh. This should be related to one of the packages in preprocess imported in preprocess_data.py.

Unfortunately, I cannot reproduce that bug. The issue you are having has nothing to do with any packages being imported. If you read the code FdcDataManager._load_data(), self.fdc_data_dic is a dictionary where the key is filename and the value is the pd.DataFrame. The fact that you encountered KeyError means that 'food' was not filled up correctly in _load_data(). This means that your data directory was not setup properly.

I am very certain this has to do with you not being able to download the CSV files from FDC using ./download_fdc.sh. I highly suggest you downloading the data from FDC again, and running the script.

Thanks Jason. I have already erased the whole directory and re-run ./run.sh. The error persists.

Let's see the code in person. Please let me know when you'll be in the lab today.

[SimonKitSangChu]

I will be available at about 6 pm.
